`Uninstall Norton AV 2004` missing in Add/Rem list

Has anyone any ideas on how to sort the above problem I encountered while working on a friend's PC today - I looked on the site and found a remover for AV 2003, but not 2004. LiveReg and LiveUpdate were still present and correct, and I know not to remove them before Norton itself. Re-installing 2004 from a CD isn't an option (only by Rescue CD which will wipe the system), all I could suggest was to `upgrade` to a Norton 2006 trial and see if that would recognise and remove the older version. This is all just so AVG or Avast can be installed on the PC in question, to get rid of the virus's - the version of Norton in question is a 2 months past the end of the subscription date.
